*****************************************************************
|
|
Info: NBR allows conflicts(one node used by more than one signal)
|
|
in the earlier iterations. In each iteration, it tries to
|
|
solve the conflicts while keeping the critical connections
|
|
routed as short as possible. The routing process is said to
|
|
be completed when no conflicts exist and all connections
|
|
are routed.
|
|
Note: NBR uses a different method to calculate timing slacks. The
|
|
worst slack and total negative slack may not be the same as
|
|
that in TRCE report. You should always run TRCE to verify
|
|
your design.
